You’ll play both sides of a £400 deal.

Sarah is buying an iPhone 15 from Marcus on a marketplace listing. You’ll talk to Vera as Sarah, switch to Marcus, do the joint sign-off, then see what happens when the phone arrives cracked.

Real Vera. Real voice mediation. Fake Stripe — no card numbers needed.

Design pending · Mock eBay listing + Pay-with-Vouch overlay

The demo should open with what looks like an eBay listing for the iPhone, with the Vouch browser-extension button overlaid in the corner.

Mock browser chrome (URL bar showing ebay.co.uk/itm/...)
Realistic listing card: photo, title, price, seller name, shipping
Vouch extension overlay button — branded, visible, clickable
Click → seeds the deal + redirects to /new with the scenario pre-loaded
Sets up the 'where Vouch shows up in the real world' framing

Iterate visually in v0 or Figma → slot the final composition into this surface
